EzyFit Settings



A number of fit properties and display settings (color, width, equation box...) can be changed either:

The actual settings structure can be displayed by simply typing fitparam.

This table lists the property names along with the type of values each accepts. Curly braces { } enclose default values.

Property Name Property Values Description
fitcolor [R G B]
or integer
or string
Color of the fit (type 'doc colorspec' for details):
- a [R G B] vector specifies a fixed color (eg, [0 0 0] is black).
- a string specifies one of eight predefined colors (full name: 'red', 'blue' etc, or single letters, 'r', 'b' etc).
- a numeric value specifies that the color of the fit has the same color as the data, but multiplied by the factor fitcolor (less than 1 for darker, larger than 1 for lighter).
Default = [1 0.5 0] (orange).
fitlinewidth integer Width of the fit line (type 'doc linespec' for details). Default = 2.
fitlinestyle string Style of the fit line (type 'doc linespec' for details). Default = '-'.
extrapol fig | data | {none} Extrapolation mode ('fig' = extrapolates the fit to the figure limits; 'data' = extrapolates the fit to the whole data limits, even if only a selection of the data is fitted (see selectfit); 'none' = no extrapolation)
npt integer Number of X points used to compute and display the fitted curve (typically 20 to 500, default=200)
dispeqmode {on} | off Display the equation in the command window.
dispeqboxmode {on} | off Display the equation box in the figure.
dispfitlegend on | {off} Display the legend (data and fits) in the figure
eqreplacemode on | {off} Equation replace mode ('off' = keep the parameter names in the equation; 'on' = replace each parameter by its numerical value in the equation).
corrcoefmode {r} | r2 | none Correlation coefficient mode: display R, R^2, or nothing.
linlogdisp {on} | off Lin/log mode display, tells whether Y or LOG(Y) is fitted.
editcoeffmode on | {off} Open the Array Editor with the fit coefficients after showfit. See editcoeff for details.
coeffarray {row} | line Array for the Fit Coefficients: 'row' or 'line' (this option is useful for copy-paste the coefficients in Excel)
automakevarfit on | {off} Call makevarfit after each fit. Setting to 'on' creates on the Matlab workspace the variables associated to the fit parameters (the variables will be overwritten if they already exist!).
maxlengtheq integer Maximum length of the equation string to be displayed in the equation box (longer strings are truncated). Set 'maxlength = inf' for no truncation. Default value = 35.
boxlocation [x,y,w,h] Location and size of the equation box (in normalized units). Default = [0.15 0.81 0.1 0.1].
whichpickdata {first} | last Which data to fit by default when several curves are present in the figure and none is selected.
polynom_coeffname string Name of the polynom coefficients. Using a '_' (underscore) at the end of the coeff name allows for using the coefficient order as a subscript (as in latex syntax). Default: 'a_'.
numberofdigit integer Number of digits for the coefficient values. Default = 5.
